Definitions

  • the invention relates to a flow meter, in particular for warm water heating systems, with a measuring element and a display element with a transparent, tube-shaped inspection glass, in whose bore an indicator rod which is connected with the measuring element is movably guided.
  • Flow meters of this type for flowing liquids are often installed in connection with warm water heating systems so as to be able to indicate the selected partial flows of the heating medium in the various conduit trains, or respectively branch lines, and to monitor them during operation.
  • the indicator scale from which the respective position of the indicator rod can be read off is applied as a line on the surface of the inspection glass,
  • the scale on the inspection glass which customarily extends vertically from the conduit pipe
  • the rotational position of the inspection glass is undetermined, or respectively the scale is not oriented in the desired viewing direction.
  • This is particularly disturbing it several flow meters for the individual branch lines are arranged next to each other on a flow distribution pipe or return collector pipe.
  • the present invention has an object, among others, to overcome deficiencies in the prior art such as noted above.
  • an essentially sleeve-shaped scale support is arranged around the inspection tube which is axially fixed in place in respect to the inspection tube, but can be rotatingly adjusted and has a lateral cutout, which exposes the view on the inspection tube and the indicator rod, wherein the cut surfaces of the cutout have scale markings next to the inspection tube.
  • Such a scale support can be simply and cost-effectively manufactured in different suitable variations.
  • By adjusting its rotational position on the finished, assembled flow meter it is possible to achieve optimal readability in every installation situation, even in crowded space situations. Since now the inspection tube itself no longer needs to be marked, it can be manufactured with reduced outlay.
  • FIG. 1 is an elevational or lateral view, partially in section and partially cut away, of a flow meter in accordance with a first embodiment of the present invention, mounted on a collector pipe;
  • FIG. 2 is a plan view along the axis of the scale support in FIG. 1;
  • FIG. 3 is cross-sectional view along lines III--III of FIG. 2;
  • FIG. 4. is a representation of a second exemplary embodiment of the present invention, similar to the view of FIG. 1 but with the paper perpendicular to longitudinal axis of a collector pipe; the left half being an elevational view and the right half being a vertical section on a plane outward from the central axis;
  • FIG. 5 a view looking along the axis, is a plan view on the left and on the right is a sectional view taken on line V of FIG. 4;
  • FIG. 6 is a cross-sectional view taken. on lines VI--VI of FIG. 4.
  • FIG. 1 shows the flow meter of the present invention, shown by way of example, consisting of a measuring element 2 and display element 3, mounted on the return collector pipe 1 of a warn water heating system. It measures the flow in accordance with the direction of the arrow A in the return of an individual branch line.
  • a measuring element 2 which is tightly screwed into the collector pipe 1, has an external screw thread for connecting a return line (not represented).
  • a rebounding plate 7 supported by an indicator rod is located in the measuring bore 5. The position of the plate 7 along the measuring bore is clearly a function of the respective flow-through.
  • the indicator element 3 is mounted opposite the measuring element on the top of the collector pipe 1. It has a guide element 11, which is tightly screwed together with the pipe 1 and supports the tube-shaped inspection tube 10 made of a transparent material.
  • the indicator rod 6 is slidingly guided in a longitudinal bore of the guide element 11. On its upper end it supports the disk-shaped pointer 8, which slides up and down in the bore 12 of the inspection tube, The restoring spring 9 is supported between the bottom of the bore 12 and the pointer 8, or respectively the indicator rod.
  • the basic construction and the mode of functioning of such a flow meter are known to those skilled in the art and need not be described further.
  • the inspection tube 10 itself does not have a scale to be read, Instead a separate, essentially sleeve-shaped scale support 16 with a longitudinal axis 24 is provided, which is arranged around the inspection tube and has a lateral cutout 18.
  • the shape of the scale support 16 in accordance with FIG. 1 is represented in detail in FIGS. 2 and 3, wherein the "supplemented" sleeve shape is indicated in dash-dotted lines.
  • the "supplemented" shape is the shape which the sleeve would have without the cut-out 18, i.e., a figure of revolution about the axis 24, in the preferred embodiment,)
  • the cutout 18 permits the view of the inspection tube 10 and the indicator rod 6 with the pointer 8 laterally over a defined angular area, Cut surfaces 20, present because of the cutout 18, which adjoin the inspection glass 10, have scale markings from which the pointer position, or respectively the flow-through value, can be read off.
  • the scale support 16 is axially positioned in respect to the inspection glass 10, but can be adjusted in its rotational position.
  • the inspection glass has a circumferential annular groove 13 near its upper end for this purpose.
  • This is engaged by a cam 22 of the scale support, which protrudes from its interior surface 21 (which corresponds to the diameter of the inspection glass).
  • the scale support which is cut along its entire height, is resilient in diameter, aided by a longitudinal groove 23 located opposite the cutout 18.
  • the scale support can be simply pushed on the inspection tube from above (axially).
  • the cam 22 slides last over the slightly beveled and of the inspection tube and then snaps into the annular groove 13.
  • the cut surfaces 20 with the scale markings are inclined with respect to the longitudinal axis 24, as can be clearly seen in FIG. 3.
  • the cut surfaces 20 on both sides need not be located in the same plane, but contrary to the example shown, they can also be inclined toward each other, for example oriented approximately radially toward the axis 24.
  • Flow meters of this type can of course also be operated with the reverse flow direction in the measuring pipe 5; an arrangement similar to the one in FIG. 1 then is mounted, for example, on the flow distribution pipe of a heating installation, wherein a flow branch line is connected to the threaded connector 4. Since in this case the flow acts from above on the rebounding plate 7, a scale support 16 is used, whose scale extends, contrary to FIG. 1, from the top to the bottom, and the restoring spring 9 must be inserted below the pointer 8 and supported on the bottom on the guide element 11.
  • the measuring element 2' and the indicator element 3' are again mounted on a return collector pipe 1'.
  • Elements 5 to 9 in FIG. 4 essentially correspond to the elements of the previous example provided with the same reference numerals, and the mode of functioning of the flow meter is basically the same as described above and known.
  • the flow meter is structurally combined with an adjusting valve (with a valve gasket, or, locking body 34 and a valve seat 35) for the flow to be measured.
  • the inspection tube 30 is not rigidly connected with the guide element 31, instead it is embodied as a rotatable ascending spindle and has the valve locking body or gasket 34 at the lower end.
  • the spindle screw thread (exterior screw thread on the inspection tube 30, interior screw thread on the guide element 31) is identified by 46.
  • a knurled ring 44 is used for the rotational adjustment of the spindle, or respectively the inspection glass about the axis 24'. It has a centered, for example rectangular or square recess 45, which is engaged by two resilient tabs 33, which protrude from the upper end of the inspection tube 30 for snap-fastening the ring 44.
  • the approximately sleeve-shaped scale support 36 surrounding the inspection tube 30 is also designed in a manner differing from the previous exemplary embodiment.
  • a lateral cutout 38 which permits viewing the inspection tube and the indicator rod, has cut surfaces 40 (inclined, for example) on which the scale markings are placed.
  • the cutout 38 does not extend over the entire height of the scale support 36, instead it leaves circumferential closed ring sections at the top and bottom.
  • An upper, radially inwardly projecting section 42 on the scale support rests on a radial shoulder 32 on the inspection tube 30.
  • the ring 44 furthermore projects over the upper end of the scale support 36. In this way the scale support is axially fixed in place, but rotatably guided on the inspection tube.
  • the scale support is widened in the shape of a bell on the bottom at 48 and provided with teeth 49 on the interior, which extend over the hexagon nut 50 of the guide element 31.
  • the scale support 36 is axially displaced along with the spindle, but remains in its rotational position.
  • a rotation orientation which is suitable for optimal reading of the scale and is adapted to the installation situation, is set during mounting of the flow meter as long as the ring 44 has not yet been snapped on and as long as the teeth 49 can be turned over the hexagon nut 50 when the scale support is lifted. The scale support then maintains the set orientation during operation.
  • An auxiliary scale 51 applied to the hexagonal nut 50 can be seen in FIG. 4, whose graduation corresponds to the pitch of the screw thread 46 and which can be created, for example, by notching the corners of the hexagon nut.
  • the respective position of the valve 34, 35 can be read off, at least approximately, from the position of the lower edge of the section 48 extending over the hexagon nut 50.
  • the scale support may comprise a transparent tube section, preferably cylindrical, without any cutout. With this tube section the pointer 8 is visible through walls of both the inspection glass 10 and the scale support. The flow-calibrated markings may then be made on the surface of the tube section.
